Was Kilmar Abrego Garcia assassinated as a damage control measure?

A growing fringe theory has begun circulating among activists and independent journalists: that Kilmar Abrego Garcia, a Salvadoran man deported during the Trump administration, was intentionally killed in El Salvador to prevent him from exposing truths that could have seriously undermined the U.S. government’s immigration narrative.

A unanimous 9–0 ruling by the U.S. Supreme Court, ordering the Trump administration to facilitate the return of Kilmar Abrego Garcia to the United States. The ruling, issued after emergency filings by human rights attorneys, stated that Garcia’s deportation had violated due process — and that credible evidence showed he had been misidentified as affiliated with MS-13.

No one has seen or heard from him since he's been deported. Has he been killed via orders of the Trump administration?
